The Siege of Petersburg - The Battles for the Weldon Railroad, August 1864, John Horn.
Focuses on Grant's fourth Petersburg offensive, the attempt to cut
the Weldon Railroad south of the city, and at the same time prevent Lee
moving troops to other theatres. Combines very detailed material on
the three battles with an interesting examination of why the Union army
performed so poorly in them, with an examination of the long term
strategic results of the constant application of pressure at Petersburg.
